When using my cedar strip (17 ft.) as a solo, which I do quite often, I've used a stadium seat. After opening it, I place it against the back thwart. With a plastic seat cover, after awhile it's getting very sticky and uncomfortable. suggestions? One day when I didn't have the seat in my truck for whatever reason I used foam. This was very comfortable until it got wet. I've seen fold out wooden seats in some canoes that look good. Main requirement is that the seats are removable and have a back -- that thwart just isn't designed for a human back. It has to have a low profile and center of gravity. JGW
